have you partitioned your sd card correctly?
http://forum.xda-developers.com/wiki/index.php?title=SD_card_partitioning
check your roms original thread to see what sort of partition you need.

which ROM do you have... and was A2SD+ part of the ROM, or sth you added?
I think I read somewhere that some A2SD+ implementations don't move the Dalvik cache over to SD. The (easiest) method to add dalvik to SD likely depends on the A2SD implementation.

Use S2E , download it from Market.
thanks.

what is better for a2SD, ony ext3 or ext3 and swap???

The a2sd script in Cool's AceS v1 does move the dalvik cache to the sd card, so most likely the card isn't formatted correctly. I suggest you use gparted or a similar tool to format your card like this: first the FAT partition, then the ext 2/3 one (note that some roms require you to have an ext 4 partition, but this is not the case of AceS; anyway, make sure you read the thread thoroughly before flashing). Also, make sure the ext partition is no larger than 2048 MB (i.e. 2 GB), since you might experience market problems. Swap is not used by most roms you'll want to flash these days, so don't worry about it too much, unless the thread mentions so.
Just to mention, S2E is only for cyanogen mod, as it's stated in the app's description, so don't use it with other roms (which have other a2sd scripts). Also, before formatting, don't forget to backup your data
Good luck!

Warm up
Hello guys!
i'm new here just want to say that it's probably the best site for modding.
I have a desire with Ginger sense ROM.

Link2sd is free on the market. Uses ext and fat partitions. I have link2sd on my Kyocera Zio m6000 which only has a total of 180mb in data and I have 137mb free. Link2sd allows you to create a symbolic link for app data dalvik-cache and lib files of the app you want to move to SD. Plus with the symbolic links you get to keep your Widgets.

Dalvik Cache will take up space on "Internal storage" by default on some A2SD + ROMs, but it can be moved
You can move this by running "terminal emulator" from the market and typing:
Code:
su
a2sd cachesd
or with adb:
Code:
adb shell
a2sd cachesd

[Q] any rom with data2ext

Hi all,
I want any sense rom with data2ext because then i got many MB free for apps.
How do i do this and is the speed acceptable?
Thank you!
Nick

easy:
1. root(if you havent already)
2. format sd-card with ext partition(like with a2sd but mybe a bit bigger partition)
3. install any rom with data2sd installed
and from my experience, no the speed is not acceptable. You will be much better off using a2sd+ which also gives you plenty of space..

yeah ok.
but i want many apps installed.. likely big games. and some games MUST be installed to the phone.. so with 10 apps my phone is fully full.
i always got like ~130mb internal.
but i want data2sd cause then you got many many mb free for apps.
+ when i installs an app and move it to my sd ext. it still leaves something on my internal memory wich takes space. so apps2sd still takes quite much space on internal memory.
so you all got this problem?

You are not understanding the difference between a2sd and froyo apps 2 sd. The last one being the one, where you can move apps freely.
The oldstyle a2sd+ moves both apps and dalvik cache to ext, so even though it says you have only gotten 130 mb, it will fill up very slowly. I myself have around 100+ apps installed including google earth and some games, and i have no problem..
edit: and no you cant move apps to ext. The app2sd in froyo is moving them to a special folder on the fat32 partition, while the oldstyle a2sd+ have the /data/app and /data/dalvik symlinked to the ext-partition, so apps will always be installed to ext using this method.

ok so i took leedroid.
and posted this in his thread:
hi all,
i got the apps2sd version.
and i got ext3 876MB.
But at the first page it says: lots of free internal memory! on the apps2sd version.
but i only got 133 mb internal mb free.
So i dont think thats much?
cause my apps cant move to sd.
some can but not all games.
so my space is limited and i really need much internal memory!!!
please someone help me!
Greetings,
Nick
EDIT: and how can i check if my apps and dalvik cache are thruly on my sdext?

OMG!
Please read my post over again.....
a2sd works by symlinking some folders to your sd-ext partition. This will NOT mean that your system will measure plenty of space. Just that those 2-3 folders will not take up space on the /data partition, so installing apps only leaves a little bit of data and thus only decreases the free space a tiny bit. 2 see this better try installing "quick system info" which will let you see how much of the sd-ext partition is used. Then go install a lot of apps and see, if this fills your phone. It should not(only a2sd storage in quick system info should be filling up).
and to check, if they are there, install an app like root explorer and check /system/sd which should show the folders present on the sd-ext partition("app","app-private" and "dalvik-cache")

Are you using a2sd+ at all or are you manually moving apps to SD via application manager?
data2ext still has not matured enough with relatively high risk of data loss atm. I have no doubt the devs are working hard on it, but it is not ready yet to go mainstream. AuraXTsense sported data2ext in 8.1., yet it has returned to good ol' a2sd. It simply is not stable enough.

[Q] RcMix/insertcoin a2sd vs cm7

hi, i was just wondering if someone can tell me the benefit of cm7 over a2sd please, im S-OFF so no problems changing, but just wanted to know the differences. and also which is better, insertcoin or rcmix??
cheers.

I think I read a possible speed increase with cm7
Different system partition sizes..
Sent from my HTC Desire using XDA Premium App

ok so what the big deal about the system partition being bigger.. what does that mean in real world case?

In the a2sd apps and dalvik are on sd because there is no much space
In cm7, apps are on SD ,but dalvik cache is on internal.
Dalvik is the virtual machine that runs on android to provide that java environment(behind that is Linux). Also internal memory is faster on read/write even from a class 10 SD card. That way we take advantage of the internals speed , which makes the Rom a lot faster. Also since the ext partition is used only for apps, there is more space available for more apps than a2sd

Cm7 does not officially support a2sd. Even if you have an ext partition on sd card, you also have to run a special script or program(strange issues occur here sometimes). This is why it's recommened to have cm7 hboot when you run cm7 rom, because with cm7 hboot you do not need a2sd because of the big /data partition.
Furthermore, as far as i know the difference between a2sd and a2sd+ is the following:
a2sd: only apps will be moved to sd card
a2sd+: apps and cache will be moved to sd card.

So. if we're in cm7, it would defeat the purpose if we use mcr scripts to move dalvik cache to sd? It's just that I noticed an increase in internal storage space. Is that not a good thing?

that is true indeed, but insertcoin gb cm7 used a2sd while the stock hboot uses a2sd+. I was talking specifically for these roms , not for cm7, but the cm7 hboot gingersense roms

Laggy Desire while opening apps

Hey,
I have extremely annoying issue on my Desire. Everytime I am opening an app there is a delay between tapping the icon and displaying app (full loaded screen of the app). Sometimes it takes 3-5 seconds. You can imagine how bothering it is. I found out that when I do full wipe it is great again but it takes less then two three days and lags are back. The biggest dealy has Handcent, Gallery, etc. Sometimes opening settings is laggy too.
Any idea how to get rid of this lags? I think it started some time after rooting my phone. Could be the problem the number of apps installed on a2sd storage? I have currently 106 apps.
I am really desperate! I love Android but this is not the user experinece I would expect from such a system and such a smartphone!!
I use GingerVillain 2.7 based on CM7. I used CM7 before and it was the same.

Do you use software like setcpu to control the cpu frequency or using scripts/software to control the voltage?

I used JuiceDefender but I had this problem before I use it. There is also some performance settings in CM7-settings. Do you think the problem is somewhere in CPU settings?

I don't think so. Given the fact that after a wipe it works fine, I'd put my money on your davlik cache. As it grows bigger in size, combined with probably low class sd card, it gets slower. You have some tips&tricks how to move davlik to /data in the development section. Or simply buy a faster sd card.

I have Kingston 16GB class4. I know that class4 is not the biggest number but I read that Kingston is as fast as some other cards class6 and that in fact it is not necessary to have so speed card This is a new want I don't really want to pay for another one...
Move dalvik to /data? Do you think this helps? And a2sd storage will work the same way?

Moving dalvik cache to internal /data partition often solves perfomance problems. That's why some developers do not move it to sd.
It won't disturb the working of a2sd, because has two different versions:
A2SD: All apps you install will be automatically moved to sd-ext
A2SD+: All apps you install plus dalvik cache will be automatically moved to sd-ext.
So when you move dalvik cache to /data, you are using "only" a2sd, but it's still working the same way.
But before this I would try wether wiping dalvik cache in recovery solves your problem.

Oh. Thanks! I will try! But I am afraid that I tried an app moving dalvik in the past and my phone got extremely laggy and buggy. Maybe it was not compatible app with my ROM
As I said when I do full wipe (so wiping dalvik as well) it is quick several days but then it gets back to laggy phone.

GV 2.7 - I have dalvik cache on Internal memory with Cm7r2 Hboot - no delays like you have, instead instant opening.
You can move it easily by using any terminal (I have better Terminal Emulator Pro).
Commands:
a2sd cachesd - moves Dalvik to SD
a2sd cachesdreset - moves Dalvik to SD, but firstly it wipes it.
a2sd nocache - moves Dalvik to Internal NAND.
a2sd nocachereset - moves Dalvik to Internal, but firstly it wipes it.
Personally, I prefer the "reset" commands.

Change your partition table. With aosp rom you waste almost 150mb on /system. That is one hefty davlik with 110 apps approximately.

[Q] The best method to to get space with desire?

Hello Folks,
Now a days we have a lot of methods to fix space lack in desire phone.
Which one is the best for you?
AD2SD?
INT2SD?
APP2SD?
LINK2SD?
Any other?

Whatever the ROM uses. They all do basically the same thing - move stuff to your Ext partition to free space on phone.

except INT2SD, it converts ur ext partition into internal memory (data partition, so yh pretty much the same) but only a few roms have it

I choice RunnyMod 7.02 thats came with INT2SD and AD2SDX, but both of them i'm not able to use it.
I hv CM7r2 HBOOT and it is recognized in Amarullz setup, also, i hv a 3GB SD Ext4 partition.
The main problem is, the script setup says that my device does not support both of them.
So, my question is, if INT2SD is better than others, I'll try to fix this, but if is pretty much the same, I wont try.
And the last not least, I cant post in dev forum, so cant explain my problem there!!!
Thanks

3gb ext partition is too big. 1gb - 1.5gb max is the recommended. maybe that is the problem

do you think my SD need to align? or Gparted does itself.

You dont need 3gb ext4 partition. Make it 1 gb, it is more than sufficient.
I have used APPS2SD and INT2SD both. But i like INT2SD more as it doesn't slow down my memory card and it allows me to install more apps.:fingers-crossed:

Int2sd the best, cause all other methods lacks of memory after ~100 apps installed.
Now I have got Elk759 JB 0.37.1 with Int2SD-S/

Sent from my HTC Desire

i felt that a2sd was faster than int2sd. it might be because i have a slow sd card. a2sd can be set to leave some parts on the internal memory keeping those parts faster

From what I understand (and while not very new to this, I am not an expert or a developer) there are three partitions that are restricted inside the internal ROM: apps, data, cache
People seem to agree that moving data to sd slows down the phone, so they tend to keep it in the internal memory. So the main difference between the scripts is if the move the data to sd or not. I think with most modern ones, this is an option and can be enabled or disabled.
As others said, int2sd or int2ext follows a different approach, but I think the principles and end result are the same.
I like the roms that apart from installing the script that runs at startup, they provide the control script that you can run from the terminal and check the status or enable/disable features after installing it.

Moving dalvik cache to sd slows the phone down, everything else can be moved.
I prefer a2sd.

Depends on ROM, mostly
Most ROM devs already indicate a perference for a2sd scripts. If I recall correctly, the first AOKP builds needed m2sd, PA prefers INT2EXT and most GB ROMs used a2sd.
As for speed, try to keep app data on internal memory. Anything else can be moved. Dalvik-cache is mostly taking up half of the internal memory, so an excellent candidate to move.
